Title: Integrated cct. matrix array of photosensitive elements - programming storage device in easily manufactured form
Inventor: MEYER JUERGEN DR
IPC: G11C17/06
Filed: 1974-05-27
Abstract: A matrix array of photosensitive elements arranged in a fixed storage format and depending on Cadium sulphide photosensitive elements is for manufacture in integrated circuit form and is for application in data processing systems when a light sensitive programme storage element is required, such as in a card reader. The device offers advantages of cheapness, compactness and convenience of manufacture over the traditional electromechanical switch matrices used for such applications. The matrix array consists of two sets of conductors deposited on a substrate, each set consisting of a number of parallel conductors, and each set consisting of a number of parallel conductors, and each set at right angles to the other. At the crossing points are deposited a diode and a Cadmium sulphide photosensitive element in series joining the vertical to the horizontal conductors. The details of various materials in addition to cadmium sulphide are given and the layout of the thin film deposited layer is examined.

Patent DE-2532338-A1 (DE)
Title: Three phase motor with frequency dependent speed control - is fitted with subdivided and discrete rotor conductors supplied from cyclo converter
Inventor: ZAHN FRIEDRICH
IPC: H02K3/12
Filed: 1975-07-19
Abstract: The wave form from the cyclo-converter is rich in harmonics. To minimise the losses produced by these harmonics in the rotor winding it is made as a two layer winding. Each coil is subdivided in both width and depth into a number of strands and is also closed on itself. The subdivision reduces the effect of harmonic eddy currents in the already known manner. The strands may all be connected in series, that is each coil effectively has a larger number of turns, or, alternatively, all the strands may be short circuited at one point. The effect of stator harmonics may also be additionally reduced by short pitching the coils.

Title: Folding, flexible, spacious exhibition system - comprises folding display boards easily handled and capable of reuse many times
Inventor: THUERMER LUDWIG PROF
IPC: G09F15/00
Filed: 1975-08-30
Abstract: Display board system esp. for use as flat surfaces carrying information, is comprised by a single, independently standing folding wall consisting of an assembly of seven large rectangular plats of light rigid material. Of these, three are as rigid support plates for the matter being exhibited, and these are joined down their long edges. Two pairs of other boards are joined so as to fold down their long edges, and they are stamped or cut so as to form a folding groove down the centre of each folding board whilst secondary folding grooves run at 45 degrees from the corners to the centre line. One of each of the paris of folding boards is glued to two of the support boards. The folding surfaces liited by the fold grooves are attached in such a way that the centre support board has a folding plate fixed on both its surfaces, whilst the outer plates each have only one plate. When the support boards are folded towards each other, the folding boards stretched between support boards move outwards along their centre lines whilst the triangular sections formed by the folding grooves move upwards/downwards and inwards. The system is simple and easily erected and dismantled by unskilled labour so that it can be easily transported and protected against damage during transport for use over and over again. The outer boards can be fitted with shelves and covered with glass or transparent plastic material.

Title: Multichannel coded radio transmission apparatus - has several oscillators which can be tuned to any one of several frequencies
Inventor: BLUM MICHAEL
IPC: H03C3/06
Filed: 1975-11-14
Abstract: The oscillator is tuned to its various transmitting frequencies by a switching unit. This switching unit is arranged so as to form part of the oscillator circuit.

Title: Integrated memory matrix programmable by external wiring - has reading storage elements on common substrate and connected by electric conductors in columnar array
Inventor: FAGAN LLOYD DALE
IPC: H01L27/07
Filed: 1976-05-14
Abstract: The common substrate has diffused into it several double emitter transistors. Their first emitter ranges are connected row-wise to first electrical conductors and their second emitter ranges are connected column-wise to second electrical conductors. Programming is performed by external feeding of a current via the appropriate row and column conductor of a transistor to an intersection for programming and by the short-circuit thus generated in at least one base-emitter stage. The supply current can be such that an emitter is short-circuited with base and collector.

Title: Narrow-band video telephone system - displays whole image whilst still allowing high resolution image area and using reduced capacity memory
Inventor: SCHNEIDER ADOLF DIPL ING
IPC: H04N7/12
Filed: 1976-05-28
Abstract: The narrow-band video telephone system displays the entire object viewed by the camera on the screen whilst still allowing areas of high resolution. This is achieved by transmitting from the receiver the wanted image area with high detail resolution but reduced movement resolution and the rest of the image with reduced detail resolution and high movement resolution. The receiver (B) has an image area generator (G) that stores the coordinates of the wanted image area (F) and transmits it via a picture channel (a) to the transmitter (A) and simultaneously operates a changeover switch (SZ, S3). The changeover switch passes the incoming picture signals outside the image area via a memory (Sp) to the crt crt. The transmitter has a detector (C) that responds to the transmitted coordinates and operates an adaptation switch (S1) within the wanted area.

Title: Radial shaft bearing bush with integral oil reservoir - locates contact roller to produce self:lubrication
Inventor: KIRMA SAFA DIPL ING
IPC: F16C33/10
Filed: 1976-06-12
Abstract: A bearing bush (1, 2) for a rotating shaft (3) is located by a bearing housing (4) which is provided with an integral oil reservoir (5). A plastic roller (7) of low specific wt. is located by a slot (6) in the lower bearing shell (2), and a central pivot pin (8). The lower half of the roller (7) floats on the oil (5) so that the highest point of the roller is pressed against the shaft (3). When the shaft (3) is rotating, the roller is rotating too, thus moving oil from the reservoir onto the shaft surface; hence the shaft bearing is self lubricating.

Title: Editing system for sound cine film - uses two tape heads and one erase head to move sound track synchronous with film for cutting
Inventor: GIGGE REINHARD
IPC: G03B31/02
Filed: 1976-06-28
Abstract: The sound cine editor has two sound heads and one erase head, with the sound heads spaced by the amount of film between the cine gate and the sound head in a projector. The erase head is placed between the two sound heads. Prior to editing the film is run backwards and the sound track is taken off the film, with the erase operating, and transferred to the other head so that the sound track is synchronous with the cine. The film can then be cut using visual editing. After cutting the film is run forwards through the sound editor and the sound track moved to its original displaced position. The editing system is simple to assemble and use. It can be fitted to conventional projectors or editors.

Title: Hammer for impact printing machine - has vibration damper located near drive lever to reduce hammer bounce
Inventor: SEPPERL HANS
IPC: B41J9/42
Filed: 1976-06-29
Abstract: The hammer for impact printing machine in office, data processing and telex equipment is operated by a drive lever (7) which has a vibration damper (9) located at right angles to the lever's direction of motion and movable against the action of a spring element (12). The lever is positionined in its rest state with the aid of an inclined surface (13) on the damper. The angle of inclination (alpha) of this surface (13) is such that the drive lever in its end position is neither propelled or retarded by the damper. In this way vibration-free operation of the hammer is achieved.
